Slim, fanless and durable, it is widely used by mobile professionals, field staff and remote office users, and remains a popular refurbished model. Its built-in lithium polymer battery is the most common consumable part after years of repeated charge cycles. This guide includes&nbsp; specs, hands-on runtime testing, installation notes and a full FAQ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dell offered two factory <a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-14-7480-replacement-battery.html\">battery options for Latitude 7480<\/a>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-14-7480-replacement-battery.html\"><strong>DJ1J0<\/strong><\/a> <strong>(42Wh, 3-cell, 11.4V Li-ion)<\/strong>\uff1aCross PN: 0DJ1J0, PGFX4, 0NF0H, 451-BBZL. This is the standard low-capacity factory battery for base configurations.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-14-7480-replacement-battery.html\"><strong>F3YGT<\/strong><\/a> <strong>(60Wh, 4-cell, 7.6V Li-Po)<\/strong>\uff1aCross PN: DM3WC, 0DM3WC, 2X39G, KG7VF, 451-BBYE, 453-BBCF. This is the high-capacity upgrade battery for the same chassis. Both batteries fit Latitude 7480 and are interchangeable. This battery family also fits Latitude 7280, 7290, 7380, 7390, 7490.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Important reminder: Do NOT confuse it with 7370 batteries (XCNR3 \/ P63NY). They look similar but have different connectors and dimensions, no cross-compatibility. Always check the PN printed on your old battery label before ordering.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hands-on Product Review<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We tested certified <a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-14-7480-replacement-battery.html\">replacement DJ1J0 42Wh and F3YGT 60Wh batteries<\/a> on a Latitude 7480 configured with i5-7300U, 8GB DDR4 RAM, 256GB SSD, FHD non-touch screen, Windows 10 Pro.

After that, usable capacity will gradually decline.<\/li>\n\n\n\n<li>Installation requires removing the bottom base cover. Before touching internal parts, power off the laptop, unplug the USB\u2011C charger, disconnect the battery cable and press the power button for 10 seconds to release residual static power. Never bend, twist or puncture the lithium polymer cell.<\/li>\n\n\n\n<li>Swollen batteries are hazardous. Stop using the laptop immediately if you spot bulging, warped bottom cover or lifted trackpad. Do not squeeze, pierce or attempt to charge a swollen battery.

Higher-wattage Dell USB\u2011C adapters work, but low-quality unbranded adapters may trigger slow charging or charging failures.<\/li>\n\n\n\n<li>Avoid draining the battery down to 0% frequently. Deep discharge damages the protection board and shortens service life.<\/li>\n\n\n\n<li>If you keep the laptop docked and plugged in all day, use Dell Power Manager to set a charge limit at 60\u201380% to slow battery aging.<\/li>\n\n\n\n<li>Run battery diagnostics in SupportAssist or use powercfg \/batteryreport in Windows Command Prompt to track capacity degradation.<\/li>\n\n\n\n<li>Keep the fanless ultrabook away from high heat, direct sunlight or soft cushions while charging. Heat is the top cause of lithium polymer battery aging. Avoid covering the chassis, as it relies on passive heat dissipation.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>FAQ for<\/strong> <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-14-7480-battery.html\"><strong>Replacement Dell Latitude 14 7480 Battery<\/strong><\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q1: Which battery part numbers fit<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-14-7480-battery\"><strong>Latitude 7480<\/strong><\/a><strong>?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Two compatible options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>DJ1J0 (42Wh, 3-cell, 11.4V Li-ion), cross PN: PGFX4, 0NF0H, 451-BBZL<\/li>\n\n\n\n<li>F3YGT (60Wh, 4-cell, 7.6V Li-Po), cross PN: DM3WC, 0DM3WC, 2X39G, KG7VF, 451-BBYE, 453-BBCF They are interchangeable on Latitude 7480.

DJ1J0 and F3YGT share the same mounting space and connector inside the Latitude 7480 chassis. You can upgrade from 42Wh to 60Wh to get significantly longer battery life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q3: My Latitude 7480 only runs when plugged in, Windows shows 100% battery. Is the battery dead?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: This is a classic failure symptom. First run Dell SupportAssist battery diagnostics and check battery data in BIOS. If the diagnostic marks the battery failed, replacement is needed. Rarely, this issue can also be caused by a loose battery connector or faulty charging circuit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q4: Can I<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-14-7480-battery\"><strong>replace dell latitude 7480 battery<\/strong><\/a> <strong>myself?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: It is internal and non-hot-swappable. You need to remove the base cover, disconnect the battery cable and remove fixing screws. If you lack electronics repair experience, hire a professional technician. Always power off and unplug the charger before disassembly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q5: Do DJ1J0 and<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-14-7480-battery\"><strong>F3YGT<\/strong><\/a> <strong>support ExpressCharge?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Original OEM DJ1J0 and F3YGT support ExpressCharge. Only certified replacement batteries with the correct smart communication chip support fast charging. Cheap generic batteries usually skip this function and charge slowly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q6: How do I check my battery health?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Two reliable ways:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Press F2 during boot to enter BIOS and open the Battery Information page.<\/li>\n\n\n\n<li>Open Command Prompt and run powercfg \/batteryreport, or launch SupportAssist to run the battery hardware scan.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q7: What charger should I use for Latitude 7480?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Dell original 65W USB\u2011C AC adapter is recommended. This model uses USB\u2011C charging, old barrel chargers are not compatible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q8: How many cycles can I expect from a<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-14-7480-battery\"><strong>new replacement dell latitude 7480 battery<\/strong><\/a><strong>?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Around 300 full charge cycles under normal office temperature. With light daily use and proper care, it can stay usable for roughly 2\u20133 years before capacity drops noticeably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q9: Is it safe to leave the laptop plugged in 24\/7?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Dell firmware stops charging once full. However, keeping the battery at 100% under warm conditions accelerates aging. If the laptop stays docked long-term, set a charge limit via Dell Power Manager whenever possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q10: What should I do if my battery is swollen?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Stop using the laptop right away. Disconnect the power adapter. Do not squeeze, puncture or force the battery out. Take it to a repair shop or authorised e-waste recycling centre for safe disposal.More info\uff1a<\/p>\n\n\n\n<figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/battery4pc.com\/product\/replacement-dell-Latitude-14-7480-battery\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-14-7480-replacement-battery.html\">https:\/\/www.pc-battery.co.uk\/dell-latitude-14-7480-replacement-battery.html<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-14-7480-battery.html\">https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-14-7480-battery.html<\/a><\/p>\n\n\n\n<div class=\"wp-block-cover alignfull is-light has-contrast-color has-text-color has-link-color wp-elements-1\" style=\"margin-top:0;margin-bottom:0;padding-top:var(--wp--preset--spacing--60);padding-right:var(--wp--preset--spacing--50);padding-bottom:var(--wp--preset--spacing--60);padding-left:var(--wp--preset--spacing--50)\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-base-background-color has-background-dim-100 has-background-dim\"><\/span><div class=\"wp-block-cover__inner-container has-global-padding is-layout-constrained wp-container-core-cover-is-layout-49249989 wp-block-cover-is-layout-constrained\">\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-ca2dd60b wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:65%\">\n<div class=\"wp-block-group is-vertical is-content-justification-stretch is-layout-flex wp-container-core-group-is-layout-d8dce8eb wp-block-group-is-layout-flex\">\n<h2 class=\"wp-block-heading has-text-align-left\" style=\"font-size:clamp(8.042rem, 8.042rem + ((1vw - 0.2rem) * 21.895), 22rem);font-style:normal;font-weight:300;letter-spacing:-0.03em;line-height:1.4\"><\/h2>\n\n\n\n<p class=\"is-style-text-subtitle is-style-text-subtitle--1 wp-block-paragraph\"><\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:35%\">\n<div class=\"wp-block-group is-vertical is-content-justification-stretch is-nowrap is-layout-flex wp-container-core-group-is-layout-0f0b95e2 wp-block-group-is-layout-flex\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/pcsbattery.co.uk\/blog\/wp-content\/themes\/twentytwentyfive\/assets\/images\/woman-splashing-water.webp\" alt=\"Woman on beach, splashing water.\" style=\"aspect-ratio:3\/4;object-fit:cover\"\/><\/figure>\n\n\n\n<p class=\"has-text-align-right has-x-large-font-size wp-block-paragraph\" style=\"line-height:1.2\"><a href=\"#\">Instagram<\/a><br><a href=\"#\">LinkedIn<\/a><br><a href=\"#\">Now<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Replacement Dell Latitude 14 7480 Battery Review &amp; Buyer Guide The Dell Latitude 14 7480 (Reg model P73G) is a premium 14-inch business ultrabook of the 7000 series, built with 7th Gen Intel Core processors.
